  6. New Concept for RDP 7.1 RDP Host Rendering RDP Client Rendering Separate host intercept for each graphics stack & client equivalents – gaps Single intercept point for all graphics – predictable and complete UX Leverages Rich Client HW and SW Lightweight Clients & Complexity Shifted to Host Can lead to better bandwidth utilization for intercepted graphics types Typically requires more bandwidth as traffic is sent as compressed bitmaps 6

  7. RemoteFX VDI Architecture Concepts Enabling Technology Customer Value Differentiating Innovation • Content and GPU independent intercept & rendering • Single GPU for multiple Hyper-V guests vGPU Full rich Windows experience • Applications run at full-speed on host Host side rendering Remoting any content • Screen deltas sent to client based on network and client availability Intelligent screen capture and hardware-based encode High fidelity user experience • CODEC designed for text and image content • Single CODEC for VDI, RDS and WMS sessions • HW and software manifestations interoperable by design Bitmap remoting and hardware-based decode Full range of client devices • Supports all USB devices. • Redirection over RDP. • No client side drivers needed. Full range of USB devices USB Device Redirection

  15. RemoteFX USB Device Redirection for VDI • Versatile • Rich and thin clients (no client drivers necessary) • Use with any RemoteFX-enabled VM • Admins control what devices can and cannot be redirected • Compatible • Works with just about any USB device • Applications are transparent to redirected devices • Integrate with PnP/Windows Update for device installs 15

  19. RemoteFX Ultra Lightweight Thin Clients • New class of Thin Client using ARM based designs • Works with Hyper-V VDI, RDSH and Multipoint Server • Running Windows CE, Linux, or in-house OS • Lower client resources • CPU: 200 – 400 MHz • Memory: < 256MB RAM, < 128MB Flash Memory • Less than 5w power • Dedicated CODEC for acceleration 19

  20. RemoteFX Sizing Guide for VDI • Based on the display resolution and workload per VM, the following number of virtual machines could be loaded on a GPU • Can load additional non-RemoteFX VMs on the same server [e.g. HP RA has 65 non-RemoteFX VMs and 12 RemoteFX VMs on a 8 core server with a single 1.5 GB GPU] * These are theoretical numbers of how many RemoteFX-enabled virtual desktops could fit on a GPU with given amount of video memory. They do not take into account the amount of GPU resources consumed by each virtual machine. The GPU resource consumption will vary from workload to workload. Actual numbers will vary based on the workloads executing in the virtual machines. 20

  21. In Closing • Questions and Answer 21

  22. Common Misconceptions About RemoteFX • The CAPEX of RemoteFX is higher because of GPUs. • The user density per server is lowered with RemoteFX. • RemoteFX scales to just a couple of VMs per GPU. • There are no RemoteFX ready servers in the market today from major server OEMs. • MS views RDSH as being of lower importance than VDI. • RemoteFX is for Aero only.

  29. RemoteFXOS & System Requirements for VDI • Hyper- V Host for VDI or RDSH • Windows Server 2008 R2 with SP1 (Hyper-V, Standard, Enterprise, and DataCenter editions) • VDI Virtual Machine • Windows 7 Enterprise with SP1 • Windows 7 Ultimate with SP1 • Remote Client Device [works with VDI, RDSH or Multipoint Server] • Windows 7 with SP1 • Devices with RDP 7.1 30

  30. RemoteFX Requirements for RDSH • Requires Windows Server 2008 R2 Service Pack 1. • To use RemoteFX on an RD Session Host server, the processor on the RD Session Host server must support Streaming SIMD Extensions 2 (SSE2). • The RDSH role with RemoteFX can run as a virtualized workload on any hypervisor, since there is no dependency on a GPU. • Off by default. Enabled via a Group Policy • Recommended if your users will ever run any Flash, Silverlight or HTML5 content 31
